Walkie-Talkies and CB Radios

FRS, GMRS, CB or VHF: pick the radio service first

The radio service decides range, power and rules. FRS handhelds are simple, low power and need no license. GMRS radios use more power and, in the US, need a license, but allow repeaters and longer range. CB radios use 40 channels around 27 MHz, suit trucks and vehicles, and reach farther with a good antenna. VHF and UHF business bands, such as 416-469 MHz listings, are for work radios. Radios on different services only talk on shared channels, so choose pairs from the same system.

Waterproofing matters outdoors, and specifications note it as not water resistant, water resistant or waterproof. A radio rated for splashes will not survive immersion. Weight matters for all-day wear, and battery type varies between AA cells and rechargeable packs. Replacement batteries and microphones are listed for specific radio models, so check the model named in the title.

Range claims, channels and accessory fit

Advertised ranges of 20 or 36 miles assume a clear line of sight, such as mountaintop to valley. On flat ground the curve of the earth limits handhelds to a few miles at best, and woods, hills or buildings cut that further. Channel counts such as 22 or 40, and listed code numbers, which are CTCSS or DCS tones, only filter which transmissions you hear on a channel; they do not make calls secret. Accessories are connector-specific: a headset or speaker microphone made for one radio model or brand usually will not fit another, so match the model named in the listing.

Questions about Walkie-Talkies and CB Radios

Can FRS radios talk to GMRS radios?

Yes, on the channels they share. Most handheld GMRS radios include the shared FRS channels, so they can talk to FRS radios there. Using a GMRS-only channel needs a GMRS radio and, in the US, a license.

How far will walkie-talkies really reach?

Only with a clear line of sight from high ground, such as hilltop to valley, can they approach the advertised distance. On flat ground the curve of the earth limits them to a few miles, and in woods, valleys or buildings range drops sharply. Higher power and a better antenna also help.

What do the codes listed with channels do?

They are sub-audible tones that mute transmissions from other users on the same channel, so you hear only your group. They do not encrypt or hide calls, and anyone on the channel without codes can still listen.
